这是一款基于 LTX2.3 视频模型 + Edit Anything LoRA + Inpaint Masked LoRA + 遮罩局部重绘 + LTX 视频条件编码 + 视频帧合成 的无痕去字幕 / 去水印 / 去乱码文字视频修复应用。用户上传一段带字幕、水印、AI乱码文字、logo 或画面遮挡的视频后，系统会根据遮罩区域对问题部分进行局部重绘，在尽量保留原视频主体、动作、镜头和背景连续性的前提下，把文字和水印区域修复成自然画面。
这条流的核心优势是：不是简单裁切、模糊或覆盖，而是用 LTX2.3 对遮罩区域做生成式修复。 它特别适合处理小云雀 / Seedance / AI视频生成里常见的字幕残留、英文乱码、中文乱码、水印、logo、贴片文字、画面边缘文字和局部遮挡。相比传统去水印，它更适合做“无痕补背景”，让修复后的区域尽量跟原视频光影、纹理和运动保持一致。使用时建议重点控制三项：输入视频决定原始内容，遮罩区域决定要修哪里，全局提示词（用来写整体画面规则）决定修复后画面应该保持什么风格。
